Читать на русскоя языкеAbstract: Operations that use simple ammonium nitrate-based explosives based face the problem of its caking when stored in the original packaging. The article discusses the issues of caking of ammonium nitrate in the warehouses of explosive materials. If no stationary explosive preparation station is available on site, it is proposed to reload the ready-made explosive from a mixing and charging machine into an underground charging machine. It is advisable to load ammonium nitrate into a mixing and charging machine using a dedicated hopper. The caked ammonium nitrate is crushed when loaded in the hopper of the mixing and charging machine, which reduces the company's costs by eliminating the construction of a specialized crushing station, and improves the technical and economic performance of loading the mixing and charging machines with ammonium nitrate. The use of mixing and charging machines designed for surface mining operations for preparation of the explosive compound with its subsequent reloading into an underground charging machine is also advisable for further charging of boreholes in underground mines. The mixing and charging machines can be used not only for borehole charging on the daylight surface, but also to expand the application scope of mixing and charging machines at the mining enterprise.
